Sierra Raises $350M Funding at $10B Valuation

Sierra, an AI startup co-founded by Bret Taylor and Clay Bavor, has raised $350 million in a funding round led by Greenoaks Capital, valuing the company at $10 billion. Founded in early 2024, Sierra specializes in customer service AI agents and has secured hundreds of clients including SoFi, Ramp, and Brex within 18 months. To date, Sierra has raised $635 million with investments from ICONIQ, Thrive Capital, Sequoia, and Benchmark. Both Taylor and Bavor bring extensive experience from their previous roles at Salesforce, Google, and Facebook, contributing to Sierra's rapid growth and strong investor confidence. The company recently announced the launch of the second year of its APX program, a rotational initiative aimed at recent tech graduates, modeled after a similar program that helped launch the founders’ own careers. This hiring effort is notable amid a challenging job market as companies evaluate the impact of AI technologies on workforce needs.
